1. Field of Invention

Military, law enforcement, fire and rescue personnel, security personnel, hunters and recreational boaters among others for nighttime surveillance in any application commonly use handheld flashlights, where a reliable flashlight is required. Nowadays, such application is highly demeaned in all anti-terrorists actions that take place at nighttime. Conditions of use are highly varied, but generally require the light to deliver a desired field of view at long distances, be reliable, durable and field maintainable in order for it to be practically used in the designed applications. Typically a flashlight is hand carried and must be completely operable using simple and easily access manual controls, which do not require the use of two hands. In prior art xenon short-arc searchlights or illumination systems, whether handheld, portable or fixed mounted, the luminance distribution of the arc has been positioned facing in the direction of the beam (cathode to the rear), to provide a uniform beam pattern when the arc is at the focal point of the parabolic reflector. When the arc is moved slightly beyond (or slightly rearward of) the reflector's focal point, the combination of a placing all available light in the high magnification section of the reflector and collecting it in a slightly convergent manner produces roughly twice the operating range as a conventional anode-forward device.

Also, all prior arts of flashlights are focusing mainly of power sources or power supply to power up flashlights. Seldom of prior arts are aiming to improve the duration of lighting source as most flashlights are used for a rather short period of time. However, it is very obviously that a flashlight with an extended duration of lighting source is so needed.

Also, seldom of prior arts providing any solution to improve the strength of lighting source for flashlights since most conventional flashlights are used for normal usages such as when lighting fixtures at home are all out during storm seasons, during camping or performing repair tasks at where lightings are required. However, at extreme situations such as searching fugitives at dark environments or when fire-fighters are try to save lives at fire, a flashlight with extra strength of lighting source would be much more appropriated.

Many patents provide flashlights which combine both a flashlight with a candle together to ensure said lantern can still light up when power source is done or batteries are all used up. However, the lighting range, lighting angles and the lighting power of a candle are minimal. Such flashlight light up by a candle will not be the most useful tool in an event of a big area.

Also, most conventional flashlights do not provide any mean of self-recharging. Most of them are solely depending on rechargeable batteries. It is not environmental friendly especially in nowadays' tendency when all man kinds are promoting the sense of protecting the environment.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

The present invention comprises a three-dimensional-type-cylinder structure body (1) and embracing three sources of lighting (2), a parabola-shaped reflector (3) and a transparent front panel (4). There are three convex lenses (5) on said front panel (4) which seal the end surface of a elastic annular nut (6). Said annular nut (6) is affixed to front end portion of said body (1) in a detachable manner.

Referring to FIG. 2, said three sources of lighting (2) comprises at least three bulbs, i.e., photo-electronic cold-cathode illuminating and energy-saving source supplied by a rechargeable battery (7) in said body (1). Regular power supply enters an inner body through an external power plug (8) via wall plug-in, and connects to an electric circuit (9) in said body (1); through a power cord to charge said rechargeable battery (7) in said body (1). An electric connective switch (10) of said chargeable battery (7) connects integrally to said photo-electronic cold-cathode illuminating source.

A rear end of said body (1) is affixed to an external regular power plug (8). There are revolving circular hole (15) in both top and bottom ends of said body (1). Said external regular power plug (8) is concealed within a chamber of a handle bar (11) when not in use. Said handle bar (11) is a rectangular cylinder structure and there is a chamber underneath therein. There are revolving circular holes (12) in front, top and bottom ends of said handle bar (11). On top part of said revolving circular hole (12), there is a rotary lock (13), at bottom of which installs a flanged buckle (14). Said rotary clock (13) runs through said revolving circular hole (12) in said handle bar (11) and said revolving circular hole (15) in said body (1).
